GAS GOVERNOR AND PRESSURE-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 416,722, dated December10, 1889. Application filed August 16, 1889. Serial No. 320,923. (Nomodel.)

To all whom, it may concern.-

Be it known that I, NELSON J. DITTO, a citizen of the United States ofAmerica, residing at Washington, in the District of Columbia, haveinvented certain new and useful Improvements in Gas-Governors, andPressore-Regulators, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to improvements in gas governors orpressure-regulators placed at or near the point of combustion, and tendsto maintain a uniform flow and consequent consumption of gas where thereis a varying pressure;

The invention consists in a metallic check or cylindrical plug, whichmay be inserted in the pillar of theburner orgas-fixture.

. This cylindrical plug is provided with an axial opening from the baseextending to two or more centrifugal antipodal or radiating passages,which lead from the axial opening to a peripheral annular space, which.space extends about one-half of the length of the cylindrical plug. Fromthe upper edge of said annular space, and at right angles to thecentrifugal passages, (though they might be placed at any angle orparallel,) twoor more antipodal or radiating centripetal passages leadto an upper axial opening, thus-causing the two currents of gas afterhaving been thrice abruptly turned in their course to impinge (against)each other just below the point of combustion.

In the accompanying drawings, Figure 1 shows a vertical central section.A is the gas-pipe; B, the brass pillar; C, the plug or regulator; c, theupper axial opening; 0, lower 1 axial opening; 0 centripetal passages; c,centrifugal passages; 0 lower bearing-face of regulator, which rests onthe upper end of gaspipe; and D,annular space. This figure (Fig. 1)shows a section of my invention as applied to the pillar of a burnerspecially proportioned for it, the upper edge of regulator slightlyconical to fit against the reduced size of the pillar and the middlesection just long enough to let the lower end of cylinder rest-on thethread end of gas-pipe.

Fig. 2 shows a detail vertical section of the regulator separate fromthe pillar or burner,

the parts indicated by letters same as Fig.

, This plug has a peripheral annular space,

equidistant from base and capital, extending.

about one-half the length of plug. From the base an axial opening passesup to two or more radiating openings, the said openings being in thesame horizontal plane,'and passing to the circumference just where theplug is reduced to form the annular space. From the upper edge of theannular space, in a' vertical plane at any desired angle to the verticalplane in which the two or more antipodal or radiating openings justdescribed lie, (which we call the centrifugal passage,) and in ahorizontal plane with the lower end of the upper axial opening, two

or more other antipodal or radiating passages are made to the upperaxial opening, which we call centripetal passages. The upper axialopening passes from the upper beforementioned horizontal plane throughthe capital or upper end of plug. The two axial openings together extendabout one-half the length of said plug, the peripheral annular space,with the openings, aifording a passage for gas from the lower to theupper axial opening. the brass pillar, so that the gas cannot passaround it. When the pillar is in place, the plug will rest on the end ofthe gas-pipe, or near it, so that the gas must necessarily pass to.theburner through the passages made in the pillar, as above described.

I do not claim a governor or pressure-regulator by virtue of theantipodal currentsimpinging each other, or by reason'of acylindricalplug made to fit in the pillars of a gasburner alone.

I do claim 1. The cylindrical governor having an axial opening extendingupward from its base, and an external annular groove and passagesextending from said groove to said base-open- This plug is made to fittightly in' ing, also an axial opening extending from its top toward thecenter, and passages connecting said opening with the said annular vgroove. NELSON J. DITTO. 5 2. Theoylindricalgovernor combiningbase andtop axial openings connected by means of horizontal passages and. by anannular groove, as specified.

In testimony whereof I affix my signature in presence of two Witnesses.
